You can use button-at if you want to be agnostic of the button (not
widget) type.  If you're only dealing with text (not overlay) buttons,
you can avoid creating markers by passing a buffer position like (point)
directly to button-type.

If you are dealing with widgets, on the other hand, you should use
widget-at and widget-type in place of button-at and button-type,
respectively.  The widget and button APIs are mutually incompatible.
